[0002] In handling traffic accidents, traffic management departments need to collect data on the vehicles involved in the accident to provide a complete, accurate, and reliable "chain of data evidence" for subsequent accident analysis, liability determination, insurance claims, and vehicle safety research. Currently, the conventional method is for traffic management departments to collect data by taking photos using handheld cameras.
[0003] Photo-based data collection is limited by the operator's skill level and the level of detail in the data collection, and there is a certain probability of missing data. Furthermore, it is difficult to piece together complete accident vehicle data from scattered photos, making analysis more challenging, and it does not have the function of simultaneous collection of multimodal data.
[0004] Now, a novel computer-synchronized data acquisition device for multimodal data of accident vehicles is proposed to solve the above problems. Utility Model Content

[0007] The information acquisition component includes a horizontal fixing rod, which is horizontally placed at the top of a concave bracket. A junction box is located below the horizontal fixing rod. High-definition cameras are fixedly installed on both sides of the bottom of the junction box. A lidar is fixedly installed at the middle of the bottom of the junction box. Fill lights are fixedly installed at the front and rear ends of the junction box. A concave bracket is fixedly connected to the top of the junction box. A handle is fixedly connected to the right side of the junction box. A wire assembly extends horizontally from the inside of the handle. Multiple sets of strong magnets are fixedly connected to the bottom of the concave bracket.
[0008] As a further technical solution of this utility model, the junction box, high-definition camera, lidar, fill light, and wire assembly are electrically connected, and the high-definition camera is symmetrically distributed about the vertical center line of the junction box.
[0009] As a further technical solution of this utility model, the main support tube and the horizontal fixing rod have the same specifications, and the external shape and size of the main support tube and the horizontal fixing rod are the same as the internal shape and size of the concave bracket.
[0010] As a further technical solution of this utility model, the top of the strong magnet and the bottom of the concave bracket are at the same height, and the strong magnets are arranged at equal intervals.
[0011] As a further technical solution of this utility model, the positioning bolt passes through the positioning pin hole and the bolt through hole, and the first hand-tightening bolt passes through the concave bracket and extends into the interior of the transverse fixing rod.

The second hand-tightening bolt passes through the internal threaded pipe seat and extends into the interior of the positioning screw eye. The size and spacing of the internal threaded pipe seat and the positioning screw eye correspond one-to-one. The positioning screw eyes are arranged at equal intervals.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the computer synchronous acquisition device for multimodal data of accident vehicles not only realizes the function of synchronous acquisition of multimodal data, but also realizes the function of easy and quick construction of support frame, and also realizes the function of easy adjustment of scanning height; (1) By setting up a junction box, high-definition camera, laser radar, supplementary light, concave bracket, handle, wire assembly and strong magnet, when in use, the main support tube, extension rod and horizontal fixing rod form a gantry, which can be pushed back and forth with the rollers at the bottom of the bottom support seat. The junction box is equipped with high-definition camera, laser radar and supplementary light and other related components to form a scanning module. The concave bracket at the top of the scanning module is fitted on the bottom of the horizontal fixing rod and fixed by strong magnet. The wire assembly is connected to the laptop computer on site. At this time, the gantry is pushed and the gantry passes through the outside of the car. The scanning module scans the vehicle below. The image information collected by the high-definition camera and the three-dimensional coordinates collected by the laser radar are combined to quickly build the actual model of the car. When collecting information on the side of the car, the scanning module is directly removed from the bottom of the horizontal fixing rod and fixed on the side of the main support tube. The gantry is pushed again to scan and collect. When collecting information on the inside and bottom of the car, the handle can be held to scan and collect. It is convenient to quickly build a complete vehicle information model and realize the function of multimodal data synchronous collection. (2) By setting up a concave seat, hinge shaft, positioning pin hole, positioning bolt, main support tube, bolt through hole, extension rod, concave bracket, first hand-tightening bolt and horizontal fixing rod, when in use, the concave seat and main support tube are hinged by the hinge shaft. First, fix the scanning module at the bottom of the horizontal fixing rod, then tighten the first hand-tightening bolt on the concave bracket to fix the horizontal fixing rod, then straighten the main support tube, and insert the positioning bolt along the positioning pin hole and bolt through hole to complete the construction, forming a set of pushable gantry frames, realizing the function of easy and quick construction of support frame; (3) By setting up a main support tube, an extension rod, an internal threaded tube seat, a second hand-tightening bolt, and a positioning screw hole, when in use, according to the actual height of the vehicle, such as an off-road vehicle or other vehicles with a large height, the transverse fixing rod can be raised. First, the positioning bolt is pulled out, and the main support tube can be laid flat. Then, the second hand-tightening bolt on the internal threaded tube seat is loosened. As the second hand-tightening bolt is disengaged from the positioning screw hole, the extension rod can be pulled back and forth along the inside of the main support tube. When adjusted to a suitable position, the second hand-tightening bolt is tightened again. As the second hand-tightening bolt is inserted into the new positioning screw hole, the relative position of the main support tube and the extension rod is fixed. At this time, the main support tube is straightened, and the height of the transverse fixing rod is also adjusted, thus realizing the function of easily adjusting the scanning height.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example: Please refer to Figure 1-5 A computer synchronous acquisition device for multimodal data of accident vehicles includes two sets of bottom support seats 1. Four sets of rollers 2 are movably connected to the bottom end of the bottom support seat 1. A concave seat 3 is fixedly connected to the top end of the bottom support seat 1. A hinge shaft 4 is fixedly connected to the inside of the concave seat 3 laterally. Positioning pin holes 5 are opened on the left and right sides of the concave seat 3 respectively. Positioning bolts 6 are inserted into the inside of the positioning pin holes 5 laterally. A main support tube 7 is vertically arranged inside the concave seat 3. Bolt through holes 8 are opened on the bottom of the left and right sides of the main support tube 7 respectively. An extension rod 9 is inserted from top to bottom at the top end of the main support tube 7. A concave bracket 10 is fixedly connected to the top end of the extension rod 9. Two sets of first hand-tightening bolts 11 are inserted into the front and rear ends of the concave bracket 10 respectively. An information acquisition component for quick information acquisition is set at the top end of the concave bracket 10. Please see Figure 1-5A computer synchronous acquisition device for multimodal data of accident vehicles also includes an information acquisition component. The information acquisition component includes a horizontal fixing rod 12, which is placed horizontally at the top of a concave bracket 10. A junction box 13 is provided below the horizontal fixing rod 12. High-definition cameras 14 are fixedly installed on both sides of the bottom of the junction box 13. A lidar 15 is fixedly installed at the middle position of the bottom of the junction box 13. A supplementary light 16 is fixedly installed at the front and rear ends of the junction box 13. A concave bracket 17 is fixedly connected to the top of the junction box 13. A handle 18 is fixedly connected to the right side of the junction box 13. A wire assembly 19 is horizontally led out from the inside of the handle 18. Multiple sets of strong magnets 20 are fixedly connected to the bottom of the concave bracket 17. The junction box 13, high-definition camera 14, lidar 15, supplementary light 16, and wire assembly 19 are electrically connected. The high-definition camera 14 is symmetrically distributed about the vertical center line of the junction box 13. The main support tube 7 and the horizontal fixing rod 12 have the same specifications. The external shape and size of the main support tube 7 and the horizontal fixing rod 12 are the same as the internal shape and size of the concave bracket 17. The top of the strong magnet 20 and the bottom of the concave bracket 17 are at the same height. The strong magnets 20 are arranged at equal intervals for multimodal scanning, which facilitates the construction of a complete model. Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the main support tube 7, extension rod 9, and transverse fixing rod 12 form a gantry frame, which can be pushed back and forth with the rollers 2 at the bottom of the bottom support base 1. The junction box 13 is equipped with related components such as a high-definition camera 14, a lidar 15, and a supplementary light 16 to form a scanning module. The concave bracket 17 on the top of the scanning module is fitted onto the bottom of the transverse fixing rod 12 and is fixed by a strong magnet 20. The wiring assembly 19 is connected to the laptop computer on site. When the gantry frame is pushed, it passes over the outside of the car, and the scanning module scans the vehicle below. The image information collected by the high-definition camera 14 and the three-dimensional coordinates collected by the lidar 15 are combined to quickly build a real model of the car. When collecting information on the side of the car, the scanning module can be directly removed from the bottom of the transverse fixing rod 12 and fixed to the side of the main support tube 7. The gantry frame can then be pushed again to scan and collect information. When collecting information on the inside and under the car, the handle 18 can be used for scanning and collection.
[0018] The positioning bolt 6 passes through the positioning pin hole 5 and the bolt through hole 8. The first hand-tightened bolt 11 passes through the concave bracket 10 and extends into the interior of the transverse fixing rod 12, which facilitates assembly. Specifically, such as Figure 3 and Figure 4As shown, the concave seat 3 and the main support tube 7 are hinged together by the hinge shaft 4. First, the scanning module is fixed to the bottom of the horizontal fixing rod 12. Then, the first hand-tightened bolt 11 on the concave bracket 10 is tightened to fix the horizontal fixing rod 12. Next, the main support tube 7 is straightened and the positioning bolt 6 is inserted through the positioning pin hole 5 and the bolt through hole 8 to complete the construction and form a set of pushable gantry frames.
[0019] The extension rod 9 has multiple sets of positioning screw holes 23 inside. Two sets of internal threaded tube seats 21 are fixedly connected to the left side of the main support tube 7. A second hand-tightening bolt 22 is inserted horizontally inside the internal threaded tube seat 21. The external shape and size of the extension rod 9 are adapted to the internal shape and size of the main support tube 7. The extension rod 9 can slide up and down along the inside of the main support tube 7. The second hand-tightening bolt 22 passes through the internal threaded tube seat 21 and extends into the inside of the positioning screw hole 23. The size and spacing of the internal threaded tube seat 21 and the positioning screw hole 23 correspond one to one. The positioning screw holes 23 are arranged at equal intervals to facilitate the adjustment of the scanning height. Specifically, such as Figure 1 and Figure 4 As shown, first pull out the positioning bolt 6 to lay the main support tube 7 flat. Then loosen the second hand-tightening bolt 22 on the internal threaded tube seat 21. As the second hand-tightening bolt 22 disengages from the positioning screw hole 23, the extension rod 9 can be pulled back and forth along the inside of the main support tube 7. Adjust it to a suitable position and then tighten the second hand-tightening bolt 22. As the second hand-tightening bolt 22 engages in the new positioning screw hole 23, the relative positions of the main support tube 7 and the extension rod 9 are fixed. At this time, straighten the main support tube 7, and the height of the horizontal fixing rod 12 is also adjusted.
[0020] Working principle: In use, the concave base 3 and the main support tube 7 are first hinged together by the hinge shaft 4. The scanning module is then fixed to the bottom of the horizontal fixing rod 12. Next, the first hand-tightened bolt 11 on the concave bracket 10 is tightened to fix the horizontal fixing rod 12. Then, the main support tube 7 is straightened, and the positioning bolt 6 is inserted through the positioning pin hole 5 and bolt through hole 8 to complete the assembly, forming a set of pushable gantry frames. With the help of the rollers 2 at the bottom of the bottom support base 1, it can be pushed back and forth. The junction box 13 is equipped with related components such as a high-definition camera 14, a laser radar 15, and a supplementary light 16 to form a set of scanning modules. The concave bracket 17 on the top of the scanning module is also included. At the bottom of the horizontal fixing rod 12, it is fixed by strong magnet 20. The wire assembly 19 is connected to the laptop computer on site. At this time, the gantry is pushed and passes through the outside of the car. The scanning module scans the vehicle below. The image information collected by the high-definition camera 14 and the three-dimensional coordinates collected by the lidar 15 are combined to quickly build the actual model of the car. When collecting information on the side of the car, the scanning module is directly removed from the bottom of the horizontal fixing rod 12 and fixed to the side of the main support tube 7. The gantry is pushed again to scan and collect information. When collecting information on the inside and under the car, the handle 18 can be used for scanning and collection. Depending on the actual height of the vehicle, such as a taller vehicle like an off-road vehicle, the lateral fixing rod 12 can be raised. First, pull out the positioning bolt 6 to lay the main support tube 7 flat. Then, loosen the internal threaded tube seat 21 and tighten the second bolt 22. As the second bolt 22 disengages from the positioning screw hole 23, the extension rod 9 can be moved back and forth along the inside of the main support tube 7. Adjust it to the appropriate position and tighten the second bolt 22 again. As the second bolt 22 engages with the new positioning screw hole 23, the relative positions of the main support tube 7 and the extension rod 9 are fixed. At this point, straighten the main support tube 7, and the height of the lateral fixing rod 12 is also adjusted.
